ARP1524A - Surface Preparation and Priming of Aluminum Alloy Parts for High Durability Structural Adhesive Bonding

Details
Document Number: ARP1524A
Revision Number: A
Title
Surface Preparation and Priming of Aluminum Alloy Parts for High Durability Structural Adhesive Bonding
Scope
This Aerospace Recommended Practice (ARP) describes the processing system and techniques for the surface preparation and priming of aluminum alloy parts for structural adhesive bonding to achieve optimum bondline durability, corrosion resistance, and manufacturing producibility. While this surface preparation has been developed and validated for two high strength aluminum alloys, 2024 and 7075, in the hardened condition it is expected to be applicable to other alloys and tempers. This surface preparation system has been validated for use with 180 degrees F (82 degrees C) and with 250 degrees F (121 degrees C) curing elastomer-modified epoxy adhesive and corrosion-inhibiting primer. The processes described herein are the result of laboratory evaluation of structural and durability performance.
